The present invention relates to improvements in ventilators and has particular reference to cow'ls for-chimneys and the *li ke.

.An important obj set of the invention isito provide ventilating -cowl which will be so mounted =as to readily respond ito air movements.

-A further object of the invention "is the provision of a cowl se foI- med-as to readily respond to th'e air currents so as Yto be1adj'usted iiraccordance with c hangesiin itheidirest-ion of' th-e wind.

:Still :an'ot herobject of the iin-venti'oniis the zprovision of 1 a cowl of the' above :oharacr ter wzhih is simple and durable off nonstruction,- eflicientiin operation and can be unannfactured at :a 'relatiyely low oost. e

Other objects and advantages 'of "the inven'tionuw ill become apparent as thedescriptionprogiresses. I

In the accompanying drawings forming a part of this specification and in which like reference characters are employed to designate corresponding parts throughout the same:

Figure 1 is a side elevational View of my improved device shown in operative position,

Figure 2 is a front elevational View of the same,

Figure 3 is a rear elevational View of the same, 7

Figure 4 is ahorizontal sectional view taken on the line H of Figure 1,

Figure 5 is an enlarged central vertical sectional view through the upper portion of the structure, and

Figure 6 is a similar view taken through the bottom of the device.

Referring to the drawings, wherein for the purpose of illustration is shown the preferred embodiment of my invention, the numeral 10 designates the upper outlet portion of a chimney or of a ventilating pipe. My improved cowl is adapted to be pivotally mounted on this pipe in the customary manner, and is turned by the wind to induce the exhaust current therethrough, and avoid back draft of foul air or smoke.

Arranged upon the upper end of the ventilating pipe 10 is a supporting number 11 comprising an annular body having an outwardly directed flange 12 at its upper edge. Extending diametrically across the body is a. support bar 13 enlarged at its center to provide a boss 14 having an opening for the lower end of the ventilator standard 15.

llhiststandard 'isii n theform of a metallic no d dficifrcul'artcross section. externally zscrew t l-niea'de'd lat lits flower :end and tapered to a point. 116 .at its i'upper end. The "lower threaded end .proj ects lthrough zt'he (boss 1410f the bar Bandrissecured'in position bynuts 1'7 on the rod, bearing against "the upper :and loweresides ofthebar. .ilhe body 111is=pro-, vided with oppositely disposed inotches :l8ito a'ccom mod'a'tebolts I9.

- Rotatabiy supported iupon the'sstandard :15 smas to he easihy :actuated by theair :currents and prevent "downward rush :of air in the ventilator pipe is 'a =ohimney hood 'or cowil :preferably formed of;-a@s'heet1metal blank. ELhe ,arear (portion of rthe blank is rolled to form a conical body portion 121 while the side :portions are extended forwardly and the upper portion is formed to provide a vane 22; The lowerwportionthusxpresents a substantially U-shaped forwardly presented hood portion 23. The lower edge of the hood portion 23 and the forward edges of the sides thereof are headed as at 24 to reinforce the structure of the cowl. This construction produces a hood which will respond to the changing air currents and cause the air or smoke, to be exhausted from the ventilator pipe or the chimney.

Firmly secured in the cowl 20 adjacent the apex ofthe body is a bracket 25 embodying an attaching flange 26, curved to conform to the upper interior portion of the cowl, having an upwardly projecting lug 27 of tapered formation formed on its central portion inserted in the crease of the vane 22. Formed integral with and depending vertically from l the lower central portion of the flange 26 is a standard engaging frame 28, a bearing seat 29 being formed at the upper end of the frame and a web 30 being formed adjacent the upper portion of the frame, The web 30 and the lower end. of the frame 28 are provided with alined openings 31 adapted to loosely engage the support standard 15. The cowl is secured to the bracket by means of bolts 32 extending through the cowl and bracket and firmly secured by suitable nuts.

When installing my improved ventilator upon a ventilator pipe or a chimney, the standard 15 is secured to the support bar 13, the rim 11 attached to the pipe, and the bracket 25 is secured to the cowl, and inserted over the upper end of the standard. The weight of the cowl and bracket will be sustained by the standard, the point 16 engaging the bearing seat 29 formed on the central portion of the flange. The cowl as sembly is then secured against upward displacement by means of a cotter pin 33 inserted transversely through a suitable bore formed in the standard. This bore and cotter pin are arranged in a position somewhat above the lower end of the frame to. obviate any binding action of the frame connection. From the foregoing description and the drawing, it will be obvious that the cowl and frame are supported upon the upper pointed end of the standard so as to provide for. free rotary movement of the cowl. struction, while presenting a cowl of durable and efliciently operable design, is extremely simple so as to reduce the manufacturing cost to a minimum. 7

It is to be understood that the form of my invention herewith shown and described is to be taken as the preferred example of the same, and that various changes as to the shape, size and arrangement ofparts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention, I claim: a i

1. A ventilating device of the class de- This 1con-- scribed comprising a cowl formed from a sheet metal blank to provide a conical back portion and side portions defining the open front of the cowl, the blank being further formed to provide a transversely rounded upwardly and forwardly extending top and the material of the blank being folded upon itself longitudinally medially of the said top to provide an upstanding vane, and means for supporting the cowl for rotation.

2. A-ventilating device of the class de scribed comprising a cowl formed from a sheet metal blank to provide a conical back portion'and side portions defining the open front. of the cowl, the blank being further formed to provide a transversely rounded upwardly and forwardly extending top and the material of the blank being folded upon itself longitudinally medially of the said top to provide an upstanding vane, and means for supporting the cowl for rotation, the said means including an upright standard, and a bracket frame secured to the under side of the top of the cowl and rotatably'fitting the standard, the said frame having an upstanding lug at its upper end held between the folds of the vane. ,r

In testimony whereof I afiix my signature.
